Monty Monitor is the world's first smart sensor for your compost

Move over Alexa and Google Home - Monty is finally here and your backyard compost bin is about to get a whole lot smarter. Syncing with our cross-platform mobile app, Monty continuously tracks your compost tell you all about it's health, how you can do it better and so much more.

Understand what's going on inside your organic waste 

Knowing exactly what's going on in your compost can be confusing. Trying to track the aerobic decomposition, pH level, nutrient ratios and all the other things inside a pile makes it even more complicated. That's where Monty comes in - simple stick the monitor in your compost, leave it there and check back in on our app to see everything that's been breaking down.

Stop smelly, soggy, messy and pest-infested compost 

Some of the biggest problems composters everywhere face are odours, pests and other gross goings-on but it doesn't have to be that way. When you compost correctly and effectively, all you should smell is delicious nutrients and all you should see are friendly little insects scurrying around. Monty helps you do that, without you having to be an organics expert.

Have fun, engage, educate and connect with your composting

Compost is pretty cool. Not only is it amazing for the environment, recycling food waste into healthy soils and sequestering emissions, it can also be a source of knowledge and fun like nothing else out there. Monty Monitor unlocks this by creating a bridge between the inner-workings of your pile and your phone.

How does Monty even monitor my compost?

We've undergone over two years of designing and developing, trialing and testing to bring you Monty Monitor fresh off our first manufacturing run that's just around the corner. Here's the top-level tech breakdown of our world-first smart compost sensor.

Data tracking and transmission

Most sensors are inaccurate, expensive or way too delicate to use in your compost. Not Monty Monitor - we use fully gas based sensing of your pile’s temperature, humidity and volatile organic compounds to ensure effective, efficient data tracking.

Wirelessly rechargeable battery

Monty Monitor makes continuous compost monitoring super simple. You just leave it in your pile and about once a month you twist off the top module for a quick wireless charge.  

Decomposition durable probe

Compost can be a pretty tough environment, especially on our sensitive sensing equipment. That’s why we made the whole enclosure strong enough to withstand any sort of organic decomposition action.

Meet the Monty users

Last year, we did an exclusive, limited-edition release of our "MVP Monty", a beta version of Monty Monitor, to the most committed composters in South-East Queensland. Their feedback has made Monty what it is today and we're so grateful to them for sticking with us through all the bugs and bumps along the way. 

Here are just a few of them, sharing their special thoughts on composting with Monty.

I was already composting heaps but Monty has helped me to balance my compost so I can do it better and faster.

My composting journey started when I was a kid so I’m super pumped to see that my Monty is giving me results.

Monty confirms what I already know, that I use more of one thing than the other, and how I can improve this. For me, it’s the whole package.

Risks and challenges

Here at Monty Compost Co, we’ve put quality, accuracy and durability at the core of our Monty Monitor design. From initial drawings and prototypes to the actual product, we’ve done everything we could to make sure that it’s absolutely perfect. We learned a lot from our MVP release, where we saw a whole bunch of device corrosion issues arising from the depths of countless compost piles. 


If we didn’t have the support of our amazing early adopters we never would have found these issues and been able to solve them. We’re super proud to say that our final design of Monty Monitor has gone through every possible test to ensure it’s functionality in every kind of compost and we’re ready to share it with you. 


Making a world-first innovation was never going to be easy but with your support, we know we can overcome any challenge. To learn more about our commitment to mitigating product risk, get in touch. 

Common questions

We get a lot of questions on all things compost, waste, sustainability and everything in between. That's why we've put together a FAQ full of all the most common ones. Odds are, if you've got a question, we've already answered here but if not, send it through so we can grow our knowledge base together.

Updating on our progress

We know that you want to know what's going on over on our end through all the ups and downs, which is why we make community communication key. One top of our semi-regular company updates on our main mailing list, every supporter who contributes to our pre-order campaign will receive special, specific progress reports pertaining to their order. 

Staying connected

Along with our email updates, we're regulars on our various means of social media and highly recommend you join us. As a small team of super committed composters, these platforms are the fastest and most convenient way to shoot us quick comments and stay connected.

Environmental responsibility

Monty Compost Co takes sustainability seriously. We wouldn't be much of an impact startup if we didn't. We don’t like products  that need to get replaced year after year and fill up our landfills. In saying that, compost is a pretty toxic environment and your Monty Monitor will eventually need to be decommissioned ... but not disposed. When Monty finally signs off, we'll be providing a free return shipment so we can recycle, restore and reuse as any components as possible to ensure a circular system.
